Guy Shilo looks at two techniques for mounting HDFS as a local filesystem:
NFS Gateway is a HDFS component that enables the use to expose HDFS through NFS3 interface so that Linux machines can mount it and access it just as a local filesystem.
The manual installation is quite cumbersome and is covered here.
Cloudera manager automates the process so we will use it. If you do not already have NFS Gateway installed in your Cloudera cluster, go to HDFS -> Instances -> Add role instances and choose a host for NFS Gateway:
Guy also looks at Fuse and runs a quick test to see which is faster.
